It says a small plane that tilted to one side on take off and then abruptly went inverted. My guess is this was a small twin engine plane that lost an engine on takeoff. If they don’t respond quickly in those planes (in most cases, depending on their speed, by shutting off the running engine as well), the power from the working engine and the drag from the non-working engine will flip the plane.

The Rutan Boomerang is a unique twin plane that can lose an engine without adverse yaw. But small twins don’t follow these design principals.
